The data reports also integrate the volume of inbound International visitors to the United States from residents of other countries using three U.S. and International government sources: the U.S. Department of Homeland Security/U.S. Customs and Border Protection I-94 arrivals program data, Statistics Canada’s International Travel Survey and Banco de Mexico travel data.
